What is Muscular Dystrophy? Signs and Symptoms
MD is a group of genetic diseases that weaken muscles and cause them to break down. It is a degenerative disorder in which the muscles become progressively weaker, may become stiff or painful, and may have difficulty functioning, requiring assistance. This deterioration is due to the loss of the proteins that are necessary to keep muscles strong, healthy, and functional. When these proteins break down, the muscles gradually weaken and die, increasing the risk of injury. MD most commonly affects the muscles used for movement – including the muscles in the arms, legs, hands and feet. It can also affect the muscles that people use for breathing and the heart. The most common types of MD occur when there is a breakdown of the proteins needed to build muscle tissue. MD is typically diagnosed between the ages of two and five. While there is no cure for the disease, there are treatments that can help control symptoms and prolong life expectancy. Duchenne and Becker Muscular Dystrophy Duchenne...
